Hi Jon,
Just to ask first of all. why are you bleeding the brakes because of a clutch problem? The systems are totally separate.
Anyway, bleeding the brakes on a Series III is no more difficult than any other car, except perhaps for access. The main difficulty for any E-type is the inboard rear brakes and you could take the opportunity to add remote brake bleeding nipples at the rear.
A pressure or suction bleeding kit is useful, but I find that even then, I normally find that finishing off with manual bleeding can help a lot. I normally finish by getting someone (my wife has just piped up and said that you need a "Lynne") to help. What I do is go to each bleed nipple in turn, I can't remember which is which, but start at the one furthest from the master cylinder, close all bleed nipples (this is after bleeding the system as well as possible by going around the points one by one), then get the assistant (in Lynnes' case, make sure you call her the beautiful assistant!), to pump the brakes several times, finishing with the pedal held down. Then release the bleed nipple and allow the flow, keep the pedal held down and tighten the blled nipple. Ensure at all times that you have a tight fitting bleed tube to reduce the risk of introducing air again.
Anyway, on releasing the nipple you will get a fairly substantial flow, tighten the nipple as soon as it stops, and repeat a few times, then do the same at each other bleed nipple, working around and ending at the one nearest the master cylinder. This always seems to remove some air from the system which I can't get from any other method and the pedal usually hardens afterward.
Don't be tempted to reuse brake fluid, it will be aerated and even if you allow it to stand for a long time to remove the air, old fluid is likely to have attracted water, which can't be removed. If you are bleeding an old system, buy and use several litres of fluid to ensure a good flush, which is important for future performance - fluid should be flushed every 2 years; usually this is overlooked but should not be.
Another thing is that if you are taking the trouble to bleed the whole system, do check that all the hydraulics, including the brake pipes and hoses, are in good condition prior to beginning - you don't want to have to do it all again a month or so later.
Good Luck,
Regards,
